I have been lucky to see these horses when they were in Dayton at the German Picnic one year.  They are massive animals who were in a 10' x 10' portable stalls & they filled them.  My horses (15.2 & 16 hands) have 10' x 10' stalls & look like ponies next to them.  Last week, I passed two of their semi trailers for the horses headed WB on 70 headed somewhere.
